Logic Game Questions

arabprodigy30

So I do not want to constantly open new discussion threads for logic games, I think it is best to make this just one and if anyone else has their own questions just keep posting here and we can all try to answer each others questions. (Just a suggestion :-) )

Preptest 7, Feb 1993 LSAT Logic Games kicked my butt today ! In particular Logic Game 3, (7 Judges, In & Out Game)

After reviewing I realized how splitting the game board makes the game so much more easier. But here is where I am still kinda stuck.

Rule 1.) If the two conservatives and at least one liberal voted the same way as each other, then both moderates voted that way.

I initially diagramed this as

If CCL -->MM
IF not MM-> not CCL

But when I saw the video of JY explaining the rules he labeled the contrapositive as

If not CCL -> not MM (little confused why he did it that way, is that not against the arrow?)
